FEED-WATER PU RIFIER.

SPECIFICATION forming part of Letters Patent No. 682,398, dated September 10, 1901.

' Application filed March 2,1901- Serial No. 49,611. (No model.)

To all whom it may concern: 1

Be it known that we, ULYSsEs S. VVOHLGA- MUTH and GEORGE R. WILLIAMS, citizens of the United States, residing at Findlay, in the 5 county of Hancock and State of Ohio, have invented a new and useful Feed-Water Purifier, of which the following is a specificaa tion.

This invention relates to feed-water precipi- IO tators'; and it has for its object to provide a precipitator for use in connection with the skimmer shown and described in our Patent No. 668,214, dated February 19, 1901, or in connection with any other specific skimmer t5 in connection with which it is operable.

The object of the invention is to provide a simple and efficient construction into which the water, with its impurities, may be introduced from the skimmer and in which the impurities will be removed by precipitation induced by the cooler water returning to the boiler, a further object of the invention being to provide a construction wherein the inflowing water will not stir up the precipitated matter, additional objects and advantages of the invention being evident from the following description.

In the drawings forming a portion of this specification, and in which like numerals of 0 reference indicate similar parts in both views, Figure 1 is a view showing the application of the device to a boiler in connection with a skimmer such as above referred to. Fig. 2 is a vertical central section of the precipi- 3 '5 tator disconnected from the boiler.

Referring now to the drawings, the precipitator includes a cylindrical casing 5, which is disposed vertical and may be supported by means of legs engaged with sockets 11 in the 40 lower end thereof, said lower end of the easing being tapered downwardly, as shown, to facilitate drawing off of the sediment through the draw-off or blow-off pipe 6, connected therewith at its lowest point. The upper end of the casing has a closure 7, held thereon by bolts 8, engaged with perforations therein and in a radial flange 9 upon the upper end of the casing, and depending from this closure 7 and concentric therewith is a flange 9' of annular form and which has a groove 10 in its lower edge, in which is engaged a cylindrical partition 12, which acts to divide the easing into an outer compartment 13 and an inner compartment 14, this partition extending downwardly for substantially half the length of the casing 5. Within the partition or within the inclosure thereof is a head 14'', which is spaced downwardly from the closure 7 and between which and the closure there is formed a receiving-chamber 15, the said partition, above this head,having openings therethrough, as shown at 16, to communicate this rcceiving-chamber with the compartment 13. As shown in Fig. 1 of the drawings, a pipe 17 leads from the skimmer 18, located in the boiler 19, and which pipe passes through the closure 7 and into the receiving-chamber 15,

whereby the water, with its impurities from the boiler, is deposited upon the head 11. From the chamber 15 the water runs out- 7: wardly through the openings 16 and passes downwardly through the compartment 13 to the bottom of the partition 12, after which it passes inwardly and upwardly through the compartment 14:, and thence through a return-pipe 20, which leads from the upper end of the compartment through the head 14, through chamber 15 and closure 7, and thence back to the boiler, which it enters at the top and through which it passes to the bot-tom, where it discharges. The water within the inclosure of the partition is of course at a lower temperature than the water passing downwardly through the compartment 13, and this cooler water cools the partition and the head 14. Thus the hot water in striking these cooler plates is suddenly chilled and the impurities are precipitated, and while the water passes upwardly around the lower end of the partition the impurities continue their downward movement and are finally collected in the tapered bottom of the casing. In order that the current of water may have no efiect to stir up the precipitated matter, a frusto'conical partition is disposed below the partition 12, as shown at 25, and rests upon an interior flange 26 of the casing with its minor end downwardly. This partition collects and directs the sediment to the compartment therebelow and prevents dlisturb- 1'00 ance of the water and precipitates in said lower compartment. From time to time the blow-01f cock on the blow-off pipe may be opened to blow off the precipitates.

It will be understood that in practice modifications of the specific construction shown may be made and that any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A device of the class described comprising a casing, an inner and an outer chamber or compartment within the casing having communication at their lower ends, a receiving-chamber at the upper end of the inner compartment and communicating with the outer compartment, an inlet-pipe leading to the receiving-chamber and disposed to discharge against the bottom thereof, and an outlet-pipe leading from the inner compartment at the upper portion thereof to insure contact of the cooler water with the under side of the bottom of the receiving-chamber to cool it. p

2. A device of the class described comprising a casing, a partition within and concentric with the casing to form an inner and an outer compartment, said partition terminating short of the lower end of the casing, a head within and adjacent to the upper end of the partition to form a receiving-chamber,

said chamber communicating with the outer compartment at the upper end thereof, an inlet-pipe leading to the receiving-chamber anddisposed to discharge againstthe bottom thereof, and an outlet-pipe leading from the inner compartment through the receivingchamber.

3. A device of the class described comprising a casing, an inner and an outercompartment within the casing having their lower ends communicating, a receiving-chamber I forming an outer compartment between it and the casing, a head within the partition forming a receiving-chamber between it and the upper end of the casing, said chamber having communication with the upper end of the outer compartment, and said partition terminating short of the bottom of the casing to permit of communication of the compartments at their bottoms, a partition in the easing below the first-named partition, said partition being disposed transversely and having acentral opening, an inlet-pipe leading to the receiving-chamber, and an outlet-pipe leading from the inner compartment through the receiving-chamber.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
